Help with rooting (or something) gone wrong on Samsung GT-N5120

[ffxtidus10]

Hi!
My neighbors (11-year old) son apparently tried to root their Samsung GT-N5120 with something called King Root(??). I don't know more than that and they asked me to fix it cause (you know computers) -.-.
The problem is that it's stuck in boot loop. It boots up and it shows the screen and all but it doesn't happen anything and then it reboots. Now what i've tried is to start it in recovery mode (Volume Up + menu button + power button) and i've tried to do a factory reset but it didn't work. From what i've read i think he has overwritten those files that the factory reset needs. So what can I do? It doesn't seem to be bricked since it starts and I can start it in both recovery mode and download mode. My computer reacts when I plug it in and tries to install drivers and so forth (but it won't show up on My Computer). So something probably can be done I just don't know what to do. Any ideas?

boots up and it shows the screen and all but it doesn't happen anything and then it reboots. Ne

when it boot ups can you work with phone (going to menu or sth)
does it reboot immediately or after some time?

If I start it normally it gets stuck a while on the animation screen, then it restarts, is stuck a while and so on. If I boot it up in recovery mode (home+power+vol up) I can navigate those menus and if I boot it up in download mode (home+power+vol down) I can navigate in those menus.

try installing king root on your computer and unrooting the device if that didn't help you can install a custom ROM through recovery or a stock ROM through Odin.

I think I would like to install a custom ROM either through recovery or through Odin (the one that's easiest). The thing is I don't really know where to begin when it comes to tutorials and such, do you have any suggestions of a good tutorial of how to do that? And if you have a link for a custom ROM (or stock ROM) that would work for this device I would reeeally appreciate it!

1. try downloading a custom recovery twrp or cwn (i myself use twrp)
2. go into your stock recovery and install the recovery you can also flash the recovery with odin informations are provided where you download the recovery
3. choose a custom rom there are several custom roms on xda choose the one you like read the first page for busgs and information about that rom
4. do a full wipe and flash the rom agian tutrials on flashing the rom should be on the first page of the rom you download
**since i have n5100 not n5120 i cannot recommond you a special rom
** be very careful you should just install the recovery and rom for your device as you said n5120 else you may hard brick the tablet.
